Securing power reliability in a stadium during peak usage periods

Segment background

Large stadiums often face challenges related to harmonic issues due to their complex electrical systems and high-power demand. They can cause various problems, including equipment malfunctions and increased energy consumption. Non-linear loads, such as electronic scoreboards, LED displays, sound systems, and lighting fixtures, draw current in a non-sinusoidal manner, resulting in harmonic distortion.

The distortions can also impose additional stress on electrical equipment, such as transformers, switchgear, and cables. Increased heat dissipation and insulation degradation caused by harmonics can lead to equipment failures, reduced lifespan, and higher maintenance costs. The resonance phenomenon can occur when the frequency of the harmonic distortion matches the natural frequency of certain components, resulting in excessive vibrations and potential mechanical failures.

Challenges at the customer’s stadium

Carlton Football Club aimed to enhance the existing facilities at IKON Park in Australia. This redevelopment aimed to establish IKON Park as the primary hub for Women’s football and the long-term headquarters of the Carlton Football Club, aligning with broader government initiatives focusing on diversity, education, health and wellbeing, equality, inclusion, and safety.

The high-power demand of the building, particularly during events and peak usage periods, placed additional strain on the electrical infrastructure. The existing power factor was below the desired level, impacting the overall efficiency and energy consumption of the building. Low power factor leads to increased electrical losses, higher utility costs, and reduced equipment performance.

Our Merus^® Solution

The selected solution was Merus^® HPQ – Hybrid Power Quality Compensator, which effectively improves power quality and reduces reactive power demand at the Point of Common Coupling (PCC). These systems were designed with expandability in mind, allowing for future scalability if needed.

Throughout the decision-making process, the availability of local engineering support from our esteemed partner Ampcontrol played a vital role. Their expertise and assistance provided valuable insights and guidance, enabling informed choices and facilitating the successful implementation of the Merus^® HPQ -system.
